There's a bit of a stink going on - even in major media - about something iOS 4's been doing. Apparently, iOS 4 has been storing a list of locations and timestamps to a hidden, but readable file in a standard database format. The locations are triangulated using cell towers, and generally aren't as accurate as for instance GPS. Still, the file is stored without any form of protection on both your iPhone as well as your desktop.

Apple ultimately comes out of this stronger, better. They are already in a position where their data-collection techniques (off of the owners' devices) is more stringent than other platforms, ad networks, and app developers... and enforce even stricter enforcement of ad networks and developers on their platform.

Even on the device side, they probably want to argue that accessing the data violates the EULA (most certainly), violates the privacy of the user legally in a way that precedes weak technological protection, and possibly violates the DMCA which they could enforce on behalf of their users. (Again, no value judgment; just an observation.)

So they get forced to testify a few times, maybe some fines in some more surly countries, and make a few modifications to something that was done in haste without much thought. And then in a few months, they can point to someone doing far worse for sleazy purposes, rather than just sloppily or stupidly, and say they care about you.

A week of silence is nothing. Apple can be quiet until WWDC if they can at least announce changes then.
